Topic: Is this a radioactive waste? (Read 374 times)

Hi there everyone. New member here. I have this chemical waste dug up from a builders building new warehouse near me in my neibourghood. Any professional can tell if its nuclear waste?? Iv taken puctures and also I took samples, they are kinda heavy. As far as I searched looks like Uranyl trioxide, but all Uranyl salts look yellow to me.Please help identify the substance or what I must do to identify it? There is also a sticky goo within one of barrels.

Such barrels are ubiquitous and yellow substances too, so I wouldn't think spontaneously of radioactive waste - only in specific locations. But neither would I feel that these barrels are at the right place there.
